' Be it known that 1, CHARLES PFANNE, of

Washington, in the county of Washington,

nin g Gows Hair and do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this speci- Iication, in which-- Figure 1 is a side elevation of the apparatu employed for preparing the hair for spinning. Fig. 2 is a planview of the upper side of the same. Fig. 3 is a vertical central section upon line atw of Fig. 2. Fig. 4 is a side elevation-of my spinning mechanism. Fig. 5 is a plan view'of the upper side of the same. Figs. 6, 7, and 8 are horizontal sections, upon lines as, z,;and 2, respectively, of Fig. 4. Fig. 9 is a vertical central section, upon line z z, of Fig. 5." Fig. 10 is an elevation of the lower portion of said mechanism, a portion of the casingbeing broken away so as to show the interior arrangement of parts. Fig. 11 is a perspective view of a drawing and twisting head detached fromthe machine. Fig.12 is a like view of the parts composing said head separated from each other; and Figs. 13 and 14 are sections, upon lines z z and z and 2, respectively, of Fig. 11.

Letters of like name and kindrefer to lik parts in each of the figures.

The design of myinvention is to enable cowhair and other similar substances to be spun into proper shape for weaving; and, to this end, it consists, principally, in the means employed for separating the hairs, and feeding equal quantities toeach of the spinning-machines, substantially as and for the purpose hereinafter specified. It consists, further, in the mechanism employed for subdividing the hair, and feeding the same to the drawing and twisting heads, substantially as and for the purpose hereinafter shown. It consists, further, in the drawing and twisting heads, constructed and operated in the manner and for the purpose substantially as is hereinafter set forth.

In the annexed drawings, A represents a casing, which has a circular form horizontally, and-vertically increases in size from its upper end downward to a point near its lower end, where it expands into a rectangular base, A, as shown. Within the casing A is journaled a vertical shaft, B, that is provided, at equidistant points betweenits journals, with radial arms b and b, that extend nearly to the walls of said casing, and alternate with similar bars, a and a, that are secured within the latter,'and extend radially inward nearly to said shaft. The, upper end of the casing A is inclosed, except whereshaft B projects upward, and at one side, where a chute, G, is connected with, and extends horizontally outward from, said casing, and furnishes a means whereby the material to be operated upon may be fed into the machine. At the outer and inner ends of the bottom of the chute G are provided rollers c and 0, around which is placedan endless belt, D, that is caused to move inward at its upper side by means of grooved pulleys c and c, that are attached to the projecting ends of said rollers, andare connected together, and to a suitable driving-pulley, E,-

by cords or belts (1, said driving-pulley being connected, through suitable intermediate gearing, with the shaft B.- At the lower end of the base A are journaled a number of rollers, F and F, which'are horizontal and parallel, and are separated by suitable spaces, as seen in Fig. 3. Upon the projecting end of each roller F is secured a worm wheel, f, that meshes with, and receives motion from, a worm or screw, G, said screw being journaled upon the outer side of the base A, and caused to rotate by means of suitable intermediate mechanism that connects it with the shaft B. Within suitable'ways immediately above the rollers F and F is placed a grid, H, which consists of a rectangular frame, provided with a series of cross-bars, hand h, that are separated by parallel spaces h and h, that have each a V shape transversely, and correspond, in number and in vertical position, to said rollers. A stud or pin, 1), that is secured upon one side and at the lower end of the shaft B, projects downward into one of the spaces hin the grid H, and, when said shaft is rotated, gives to said grid a reciprocating motion in a horizontal plane, and in a line having a right angle to the line of the rollers.

The machine thus constructed is placed at some :distanceiabove the spinning-machines,

v to be hereinafter: described, and is connected I with each of the ""latter b y means of ane'nd less belt, I, that passes around one of the t rollers :11, and around a similarroller attached 7 machine.

1 ,K, from which extend upward four posts or A Y staudardsph and L, that are connected to? gether attheir upper ends by means of a hori+ i 0 1; p ate, M. Upon the upper side of the plate M isv secured diagonally a rectangular frame, N, Within which is jou-rnaled twohori-u rzontal shafts, 0 and-,O,that are each provided,

, with several seriesv of radial arms, 0 ando, and

are connected together by means of two engaging gear-wheels, whichareattached tothe pro-v jecting; ends ofsaid shafts. Between and pair: allel with the shafts O and O is placed a-bar,

Q, that is stationary, and :is provided. upon opposite sides withhorizontally and radiallyv between thearmsio and Y within p j ing rms a q, h ch arms extend nearly to said shafts, and areplaoed midway ,Motion is impartedto the shaftsorieeders Oand O by means of a vertical shaft, R, that is journaled centrally'withinithe machina'and;

' is provided at its ,upperend with a gearwheel,

S, which meshes with a similar gear wheel, T, that is attached to, and revolves with, a sec: ond shaft, U, said latter shaft being journaled. am able bear ngs attached to t m frame, and having a. 'bevel pinion, V, lth'at meshes with a similar pinion, W, that is secured upon the end of one of said shafts 0. At opposite corners of the frame N are provided two standards, X and X, within which are journaled the roller Y, around whichv passes the endless belt or apron I, that conveys material from the picker, which material passes through. a suitable opening in a sheetmetal housing, Z, that covers the feeders O O and o 0, and falls upon the latter. The lower end of the shaft R is secured within a hollow metal drum, A, that rests within suitable bearings, and is capable of revolution in a; horizontal plane, said drum being adapted externally to receive a belt for driving the machine. From the upper side of the drum A three standards, B, extend upward, and have; attached to their upper ends a drum or casing, 0, that has externally a general oylindrical form, with recesses-o and c for the reception of said standards, and at its upper end fits over a dependent flange, m, that surrounds a centrally-located circular opening in the plate M. Within the lower portion of the upper drum 0 are placed three or more fooders, D, (shown in Fig- 6,) that. have the same general construction as that before described, (shown in Fig. 5,) are arranged radially, andare operated by means of a gear-wheel, d, that is of each feeder, 'and mesheswith aycircularw rack, E, which is suitably attached to the 7 standards Land L, said drum and feeders being rotated around and with the shaft R, while said rack :is stationary Immediately below each feeder Dthe drum or casing O is extended downward in theformfof 'ajfimneh shaped chute, through which the material be twisting head, that is constructed as follows:

ing operatedupongpassestoagdrawing and 1 Two gear-wheels, F and G, are'journaled wh'eel GEare journaled: two rollers, I and l, which arecovered, preferably, with an elastic material, andhave the ,quite in contact. I

I Upon the projecting en upon the same bearing,'H, that its secured'to andextends upward. from the upper faceLof the I drumA", andv have each an independent ma I tion. Upon theupper face of the'upper gearir peripheries nearly or d of one roller, l,:is "secured a spur-gear wheel, K, that has such dimensions as to enable ill? to mesh with a toothed' ring, f, thatis formeduponthe upper; face of the lower gear-wheel F, a suitable slot, ;g.,being provided within the upper gear-wheeh 5G for the passage of said, gear K. Upon a jline, horizontally, with the gear-whefels F and have each an independent rotary motion, The gl wrr toothed ringL. is moved in the direction of theshaft It and driving pulley or drumA by a worm,jN, that engages with the toothed periphery of said ring, and, by means of suittoothed rim, a, that is provided upon the periphery at the upper end of said drum. The iupper toothed ring is, in alike manner, driven "forward or backward, or is held stationary, as may be required. As thus arranged, the motion of thedrum A causes the drawing and; itwisting heads to rotate around its axis, theupper ring M causes each head to rotate jaround its own center, while the lower ring, foperatin g th rough the lower gear-wheel F and spur-gear K, causes the feed-rollers I and I ;to rotate inward and downward, the relative motion of said rollers and of thetwisting-head ,around its own center being varied by the relative motion of the toothed rings. The bearing 1H of each twisting-head is hollow, and, at its lower end, opens into the upper end of a chute, Y 0, that extends downward and toward the cen- Q ter, as shown in Fig. 9, where it terminates im- {mediately over the center of a pair of elastic irollers, P and P, that are connected, through isuita-ble gearing, with the driving-drum A, Band have an inward and downward motion.

. The device is now complete, and operates as ffollows: The material to be spun, preferably icow-hair, having been suitably colored, ispassed through the picker, where the hairs be {come thoroughly separated", after which said Ematerial is conveyed toand deposited upon secured upon the projecting end of one shaft ithe feeders at the upper end of the spinning- ;able intermediate gearing, is connected with a G are placedtwo externallyand internally. toothed rings, L and M, respectively, which srings engage interiorly/ with said gears,'and are journaled within suitable hearings, so as to J machine. The feeders pass the cow-hairdownward into the upper drum, where it is divided into three equal portions, and, by means of the lower feeders, is passed downward to the drawing and twisting heads, which latter twist said hair and draw it downward with such speed as may be desired. The more rapid the motion of the rollers with relation to the motion of said head, the less said hair will be twisted, while a decreased relative motion of said rollers will result in a harder twist of said hair. From the revolving, twisting, and drawing heads the threads pass downward to the stationary head, where they are united and twisted into one thread, and from thence pass to the winding mechanism in a condition to be woven.

Having thus fully set forth the nature and merits of my invention, what I claim as 'new' 1sa 1. The casin g A and A, provided with the radial bars a and a, the shaft B, b, and b, journaled vertically within said casing, the grid H, h, and h, caused to reciprocate by means of the eccentric stud b, and the rollers F, which carry the feed-belts I and I, said parts being con-. structed and combined to operate in.the manner and for the purpose substantially as specified.

2. The feeder-shafts O 0, casing O c, and feeders D ,constructed as shown, and relatively arranged and operated in the manner and for the purpose substantially as set forth.

3. The drawing and twistingheads,consisting of the gear-wheels F, f, G, and g, journaled upon the bearing H, the feed-rollers I and I, and the gear-wheelsK, said parts being combined with each other, the drum A,

and the toothed rings L and M, having relatively different motions in a horizontal plane, substantially as and for the purpose'shown and described.

In testimony that I claim' the foregoing I have hereunto set my hand this 13th day of May, 1874.
